Javax.Net.Ssl.Sslhandshakeexception: Sun.Security.Validator.Validatorexception: Pkix Path Edifice Failed: Sun.Security.Provider.Certpath.Suncertpathbuilderexception: Unable To Detect Valid Certification Path To Requested Target
If you lot are working inwards Java spider web or enterprise application which connect to whatsoever other spider web server using HTTPs you lot mightiness convey seen the "javax.net.ssl.SSLHandshakeException". This is ane of the detail instance of that error. If you lot know how SSL as well as HTTPS works that when a Java customer connect to a Java server the SSL handshake happens. In this steps server render certificates to confirm it's identity, which as well as hence customer validates against the origin certificate he has inwards its truststore. If Server render a certificate which cannot last validated against the certificates a browser or Java customer holds inwards its truststore as well as hence it throws the "sun.security.validator.ValidatorException: PKIX path edifice failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to detect valid certification path to requested target".
In other words, piece connecting to whatsoever website or server using SSL or HTTPS inwards Java, sometimes you lot may confront a work of "unable to detect valid certification path to requested target" exception as shown below:
javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException: PKIX path edifice failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to detect valid certification path to requested target
The argue of this mistake is simple, certificates returned past times Server during SSL handshake is non signed past times whatsoever trusted Certification Authority(CA) which are configured inwards you lot JRE's truststore e.g Verisign, Thwate, GoDaddy, or Entrust etc.
Instead, Server is sending a certificate which is unknown to JRE as well as that's why it's non able to validate those certifications against the someone fundamental he fit inwards his truststore.
If you lot remember, at that spot is a subtle difference betwixt keystore as well as truststore inwards Java. Even though, both stores certificates, keystore is used to shop your credential (server or client) piece truststore is used to shop others credential (Certificates from CA).
This could also hap when Server is sending certificate from other certificate control which is non configured inwards JRE's truststore i.e. about internal certificate signed past times your company.
I got the just same mistake piece connecting to our LDAP server using SSL from my Spring Security based Java spider web application. Since LDAP server was internal to the company, it was sending internally signed certificates which were non acquaint inwards the Tomcat's JRE (Java Runtime Environment).
To solve this work you lot remove to add together certificates returned past times the Server into your JRE's truststore, which you lot tin create past times using keytool or other tools provided past times your company.
"Loading KeyStore jssecacerts...
Opening connectedness to stockmarket.com:636...
Starting SSL handshake...
No errors, certificate is already trusted
You are done, similar a shot if you lot endeavor authenticating against same LDAP server you lot volition succeed. You tin also configure the path of the JRE used past times your application e.g. if you lot are running your application within Tomcat, as well as hence you lot must give the path to the JRE used past times Tomcat. You also remove to configure HTTPS inwards Tomcat, which you lot create past times next steps given here.
Here is also a prissy diagram which tells what just happens when a Java customer connect to Java server using https or SSL i.e during SSL handshake:
By the way, this is non the solely agency to add together certificates into truststore. You tin also role the keytool to add together certificates into trust shop every bit well. The keytool comes amongst JDK installation as well as you lot tin detect it within the bind directory of JAVA_HOME.
This solution is especially useful when you lot don't convey the certificates used past times Server. If you lot tin contact your infra guys or Linux admin to acquire certificates as well as hence you lot tin role keytool to add together those into truststore every bit shown below:
$ keytool -import -alias -ca -file /tmp/root_cert.cer -keystore cacerts
You tin encounter here for about to a greater extent than examples of using keytool control inwards Java e.g. listing all certificates it has currently etc.

To solve this work you lot remove to add together certificates returned past times the Server into your JRE's truststore, which you lot tin create past times using keytool or other tools provided past times your company.
How did I solved this Problem?
Nothing fancy, I role an opened upwards source programme called InstallCert.java to add together certificates returned past times the Server into my JRE's truststore. I simply ran this programme against our LDAP server as well as port. When it showtime tried to connect LDAP server using SSL it threw same "PKIX path edifice failed" error as well as and hence prints certificates returned past times LDAP server. It volition as well as hence inquire you lot to add together Certificate into keystore simply give certificate position out every bit appeared on your shroud as well as it volition as well as hence add together those certificate into "jssecacerts" within C:\Program Files\Java\jdk1.6.0\jre\lib\security folder. Now re-run the programme that mistake should last disappeared as well as it volition print:"Loading KeyStore jssecacerts...
